Intel 8700K NVidia GTX 970 Ubuntu 20.04.1 Kernel 5.4.0-45 Gnome 3.36.3

I'm having issues with my VMs (virtualbox) since the 20.04 update.

Ever since the update, VirtualBox VMs stopped working. I'm getting an error message:

Kernel driver not installed (rc=-1908)

The VirtualBox Linux kernel driver is either not loaded or not set up correctly. Please reinstall virtualbox-dkms package and load the kernel module by executing

'modprobe vboxdrv'

as root.

If your system has EFI Secure Boot enabled you may also need to sign the kernel modules (vboxdrv, vboxnetflt, vboxnetadp, vboxpci) before you can load them. Please see your Linux system's documentation for more information.

where: suplibOsInit what: 3 VERR_VM_DRIVER_NOT_INSTALLED (-1908) - The support driver is not installed. On linux, open returned ENOENT.

When I do install virtualbox-dkms, the NVidia driver stops working and needs reinstallation. When I reinstall the NVidia driver, virtualbox stops working... endless loop.

I'm not sure which display server is running anymore on this system.

ps -e | grep tty
   1536 tty1     00:00:00 gdm-x-session
   1538 tty1     00:00:02 Xorg
   1785 tty1     00:00:00 gnome-session-b
   2730 tty2     00:00:00 gdm-x-session
   2732 tty2     00:05:01 Xorg
   2740 tty2     00:00:00 gnome-session-b

I guess Xorg.

This computer is running Ubuntu since 2010 (10.04) and was updated to latest versions with every iteration LTS and non-LTS since then. Never reformatted even when I swapped the entire motherboard-cpu-gpu when I changed hardware. Just dropped the SSD into the new hardware and it just booted up. Twice... While also planning right now for a third transplantation of the SSD to the latest mobo-cpu-gpu system (intel/nvidia)

Anyone facing similar problems? Anyone have a solution? How can I install the latest NVidia driver and virtualbox-dkms and have them work without one crashing the other everytiem??

Running Ubuntu Gnome 19.04 and getting the following popup. (sorry, computer not responding for proper screenshot)

So far I tried reinstalling the Ubuntu Gnome Desktop, even mysql-common.

What was changed before this error: I moved the datadir of MariaDB10.4 to a different drive, but that was 4 days ago, and since I rarely reboot I did not notice this problem until today when I had to restart.

The folder exists with permissions:

drwx------ 2 mysql root    4096 Αυγ   1 23:23 auth_pam_tool_dir

and the siblings on the same directory are root:root so is ., .. is mysql:mysql

Now I have to use the ugly (sorry) Cinnamon desktop and wait for a solution.

Main question:

Is it even possible to be be infected with a bot/spamming software on Ubuntu (or any other distro)?

Details:

My ISP blocked my port 25 (and 465) for outgoing connections (outbound connections, from home to remote server) to SMTP, so I can't use my business emails from home right now. Their reasoning for blocking me is: "because of you sending spam" which I'm not and they told me that if I'm not sending then my OS is probably infected...

I could use a comprehensive list of tools and guides to check the system (Ubuntu 13.10 14.04 64bit) for any infiltrates/malware/rootkits.

P.S.

• I also have Windows 8.1 (64bit) installed just because I also like to game on my home computer... but that's what I only do on Windows...when I have time...

• Wireless is off and even if it's on it's pass protected.

• Scanning of windows didn't reveal anything nor should have since
  there's windows and games installed there.

• I can connect to other ports for SMTP but our server uses 25 and that cannot change

• I also tested connecting to port 25 from windoze (using thunderbird)

• I use thunderbird for email client on ubuntu and tested a few others just to verify that it was not a misconfig of thunderbird.

• Telneting also outputs connection timeout...

EDIT: My ISP still refuses to unblock me... Maybe I'll have to open up 587 on the server, since that isn't blocked at the moment (I can still use Gmail)

EDIT 2:

I guess today I was connected with another tech from my ISP's support and told me that there isn't a block from them... I was furious!!! I don't know what was the previous tech doing... maybe he is new and was reading from a script..

So I tested another ISP via tethering from my phone and I successfully managed to send emails through port 25. Essentially I didn't change anything, only the ISP. Are they kidding me? Maybe the tech-support doesn't know how to interpret what they looking on their screens for my account or could it be something else?

Another step I took was to fully reset my router to it's default settings and get another dynamic IP. Still no connection to port 25.

I'm planning to get a used router from some friend or something to test with another router just to be sure the problem lies with my ISP.

EDIT 3: It's been awhile since my last update to this question. I moved back to my old house (which is in a different part of the country) where I have the same internet provider. The same company!! My settings just work as expected. I can send emails just fine using port 25. I bet the problem was with that nasty ZTE router that the ISP hands out to new customers.
